Water Processing Plant

Overview.

All of the plant functions from the ‘Inlet Works Wet Well’ through the ‘Inlet Screens’ to an ‘MBR Plant’ and on to Final Discharge.

The PLC continuously monitors the ‘Inlet Works Wet Well’ level via Ultrasonic
level measurement. Two submersible pumps are controlled in a DUTY / STANDBY configuration and are started automatically at variable pre-programmed levels (normal and storm surge operations).

The ‘Inlet Screens’ processes the raw sewage flow from the inlet works variable speed pumps. The PLC controls all aspects of the inlet screens for both normal
and storm surge operation, automatically switching as required.

The ‘MBR Plant’ treats and filters the sewage before allowing the ‘clean’ filtrate
to pass on to permeate holding tanks before discharge. All functions of the ‘MBR Plant’ are controlled by the PLC, including the periodic cleaning by either air
scour or chemical cleaning. Chemical cleaning includes preparation and dosing
of product.
